You could give the introduction yourself. But that's a high-risk choice. You have to look right, you have to sound right, you have to make sure you don't stutter at the microphone. You have to look out at a sea of celebrities in Monique Lhuillier silk pantsuits and keep your nerve.
If anything goes wrong, it will be completely and entirely your fault, with no one else to blame.
Whatever you do, you can't afford to wait long. You're nearly out of time to set this up.
